Можете ли помочь настроить node для lavalink.py?

Question

[RAINGM]

В самом коде бота всё нормально.

А питон тут каким боком?

[RAINGM]

Вадим Шаталов, сам код бота, но он отношения не имеет, исправлю

Answer 1

[Вадим Шаталов]

has been compiled by a more recent version of the Java = был скомпилирован более поздней версией Java
джаву апни

[RAINGM]

Просто обновить до ласт версии?

[Вадим Шаталов]

Сложно обнови, с приключениями,
Не видно до какой версии из трейса - но апнуть надо

[RAINGM]

[Hanneman]

RAINGM, это для той версии, которая установлена. Версию саму (релиз) надо поднять. Текущую версию покажите через java -version в терминале.

[RAINGM]

[Hanneman]

RAINGM,
1. Можно в комментарий текст - зачем картинками?
2. У вас установлена версия Java 8, в то время как последняя рекомендованная LTS-версия - 11, ну а самая последняя - Java 14

[RAINGM]

Hanneman, всё равно тоже самое

java.lang.UnsupportedClassVersionError: lavalink/server/info/AppInfo has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

[Hanneman]

RAINGM,
52 = Java 8
53 = Java 9
54 = Java 10
55 = Java 11

И что значит "всё равно тоже самое"? Вам же пишут "this version of the Java Runtime only recognizes class file versions up to 52.0", т.е. до Java 8. И это пишет вам Runtime Java 8.
Вы не написали. обновили ли вы Java, если да, то запускайте, используя путь для новой Java, потому что Runtime у вас все равно пока Java 8.

[RAINGM]

Hanneman, спасибо, всё заработало, указал путь в Path
